Figure 1 shows a device of heating 10 configured as induction cooking field. The heating device 10 has a fixing frame 12 for fixing to a work plate, a cooking plate 14 for the placement of kitchen battery elements and a panel of knobs 16 to start, stop and adjust operation of heating. On the cooking plate 14 two are arranged objects 18, 20 configured as a pot, each of which is schematically represented by plotting a circular line To carry out a cooking operation of the heating device 10, this is provided with a set of heating modules 22. These each comprise a means heating 24 configured as induction coil, which is schematically represented in figure 1 by a rectangle drawn in dashed line. In an operation of a heating module 22, the heating means 24 of said heating module generates a heating signal configured as an alternating magnetic field, which presents a heating frequency that amounts to 25 kHz, for example. The heating signal H induces electrical currents in the base metallic objects 18, 20. These electric currents they heat a food found in objects 18, 20. During operation of the heating module 22 correspondingly, a heating means 24 is fed to the heating signal production with an electric current alternate, which oscillates with the heating frequency. For the production of this alternating current and for the supply of power to the heating means 24, each of the modules heating 22 is provided with a power unit 26 configured as an inverter. These power units 26 are represented in figure 2.

The heating device 10 is provided for heating objects 18, 20 by means of a group operation of heating modules 22. For therefore, each of the heating modules 22 is provided with a sensor means 25 shown in Figure 3, through which  can identify if heating module 22 is covered by less partially by one of the objects 18, 20. By means of a grouping process that is not described in more detail is they form heating groups of heating modules 22, each one of which is assigned to one of objects 18, 20. If a user starts a cooking operation of the device heating 10 via the control panel 16, this operation Cooking is carried out by heating modules 22 of both heating groups, while the other modules heating 22, which are not part of any of the heating groups formed, remain un powered. Yes the user moves one of the objects 18, 20 on the plate of cooking 14 or place another kitchen battery element on the cooking plate 14, groups of are adapted or reformed corresponding heating of heating modules 22 through the new arrangement of objects to be heated with respect to heating means 24. The processes of grouping for the formation of heating groups have by means of a control unit 27 configured as a microprocessor, which is represented in figure 1 by dashed line.

A top view of a heating device arrangement 28 of the heating device 10 is shown in FIG. 2, in which the heating module assembly 22 is recognized. Each of the heating modules 22 has one of the means of heating 24 configured as induction coils, which are schematically represented in the figure as drawn rectangles, and one of the power units 26 represented by means of rectangles drawn in a broken line and made as an inverter. During operation of the corresponding heating module 22, these power units 26 generate an alternating current with the heating frequency by means of connection processes, which are produced by connection elements 30 (Figure 3). These connection elements 30 are configured as connection transistors. In this example, the power units 26 each have a pair of connection elements 30 made as IGBT ( Insulated-Gate Bipolar Transistor or bipolar transistor with insulated gate electrode). Likewise, alternative embodiments of the connection elements 30 are conceivable, such as by way of FET transistors (field effect transistors). From figure 3 a representation of one of the heating modules 22 with a power unit 26 can be extracted, which has the connection elements 30, a heating means 24 configured as an induction coil, and one of the sensor means 25 .

Also, the heating modules 22 are arranged in a matrix arrangement. In this example, the Matrix layout presents four rows 32.1, 32.2, 32.3, 32.4 and twelve columns. Other embodiments of the array layout with other combinations of column numbers and of rows. The heating means 24 configured as a induction coils are housed in a carrier medium configured as carrier matrix 38 (see also figure 5). The heating modules of each row 32.1, 32.2, 32.3, 32.4 fix a row axis, where the row axes are aligned in parallel with respect to an axis 34. The heating modules 22 of each column fix a column axis, where each of the column axes is aligned parallel to an axis 36 that runs vertically with respect to axis 34.

During a module operation heating 22, heat is generated through the power unit 26 corresponding, especially through losses of connection elements 30 of said power units. In a group operation of the heating module set 22, the heat generated by a module heating group heating 22 driven must be evacuated in order to avoid an overheating of the heating device 10. To avoid deterioration of the electronics of the device heating, especially the temperature of the heating device 10 below the value of 125 ° C. For thus, the arrangement of heating device 28 is provided with a cooling unit 40. The unit of cooling 40 has two units of cooling bodies 42, 44, each of which is arranged below the matrix carrier 38, seen from the cooking plate 14. Each of the units of cooling bodies 42, 44 comprises two bodies coolers 46, 48 and 50, 52 respectively, made in a single piece and made of aluminum. Each of the units of bodies chillers 42, 44 serves to cool two rows 32.1, 32.2 and 32.3, 32.4 respectively of heating modules 22, which correspond to two rows of the provision of matrix. The cooling body units 42, 44 serve in special for cooling the power units 26 of the heating modules 22. For this, two corresponding rows of power units 26 are arranged in parallel with with respect to axis 34 of the array arrangement and on both sides of one of the units of cooling bodies 42, 44. The units of cooling bodies 42, 44 are configured identically, of so that the description below is limited to the unit of cooling bodies 42.

Each of the cooling bodies 46, 48 is configured as a parallelepiped shaped body (see also figure 4), which extends in the assembled state of the arrangement of heating device 28 along the axis 34 of the array arrangement. Also, each of the cooling bodies 46, 48 have a contact surface 54 and 56 respectively (see also figure 4), through which said bodies are in contact with each other. Each of the contact surfaces 54, 56 is formed by a surface side of the corresponding cooler body 46 or 48, which extends vertically with respect to the direction of the extension main cooler body 46 and 48 respectively. The contact surfaces 54, 56 are configured so identical, through which a transmission of effective heat between the cooling bodies 46, 48. During a operation of the corresponding heating modules 22, lateral surfaces of the cooling bodies 46, 48 serve to cooling of power units 26. In this case, a lateral surface 58.1 of the cooler body 46 shape in action together with a side surface 60.1 of the cooling body 48 a heat absorption zone 61.1 for heat absorption generated through power losses by the units of power of row 32.1 of heating modules 22. This zone Heat absorption 61.1 is configured as a surface of related heat absorption that extends in the direction of the main extension of the chiller unit 42. In this embodiment causes heat absorption to through direct contact and, more specifically, through a contact of power units 26 of row 32.1 with the zone of heat absorption 61.1. In another example of how to realization, this can happen indirectly, in which the power units 26 are arranged with a small distance with respect to the heat absorption zone 61.1. That's it thinkable the use of a heat conduction medium, as per example a heat conductive paste, for the connection of the power units 26 with heat absorption zone 61.1.

A lateral surface 58.2 of the cooling body 46 forms in joint action with a lateral surface 60.2 of the cooler body 48 and on the side of the body unit chillers 42 opposite side surfaces 58.1, 60.1 a 61.2 heat absorption zone configured as the surface of related heat absorption, which serves for cooling of row 32.2 of heating modules 22. The zones of heat absorption 61.1 and 62.2 form an absorption zone of heat 61 of the cooling unit 42, which serves to cooling of rows 32.1 and 32.2 of modules heating 22. The description of the formation of zones of heat absorption through the chiller unit 42 It is also applicable to the chiller unit 44 and is not repeated

In a group operation of the modules heating 22, the heating module set 22 it is distributed between the heating groups and the rest of heating modules 22 that remain un powered. TO through the large heat absorption zones 61 that are extend interrelatedly throughout the length of the rows 32, can be evacuated through areas of the units of cooling bodies 42, 44 directed towards heating modules 22 not activated a heat generated by the power units 26 actuated heating groups. In this case, during a group operation of heating modules 22 se you can get a quick and effective temperature compensation between regions of the cooling body units 42, 44 which correspond, on the one hand, to the heating groups and, for other part, to heating modules 22 not activated.

Also, the cooling unit 40 is provided with two fan units 62, 64, each of the which is assigned to a unit of cooling bodies 42 and 44 respectively. In this case, each fan unit 62, 64 Serves in joint action with the cooling unit 42 or 44 corresponding to the joint cooling of two rows 32 of Array arrangement of heating modules 22. Each of the fan units 62, 64 has two fans 66, 68 and 70, 72 respectively, which are willing to both sides of the cooling unit 42 42 assigned. Every one of the fans 66, 68, 70, 72 is arranged in the area of a front surface 74 of a cooling body 46, 48, 50, 52, the which extends vertically with respect to axis 34 of the array arrangement (see figure 4). During operation of the heating device 10, each of the units of fan 62, 64 generated by its fan pair corresponding a stream of cooling air 76 flowing in the address of the main extension of the body units coolers 42, 44 in parallel with respect to axis 34, and which is represented schematically by an arrow drawn in dashed line. To do this, fans 66, 70 aspire to a cold air and blow it to the cooling unit units 42 and 44 respectively. The fans 68, 72 suck the heated air in the unit of cooling bodies 42 and 44 respectively, and what They evacuate out. Seen from the hob 14, each of fans 66, 68, 70, 72 is covered by an area partial 78 of a unit of cooling bodies 42, 44, which is  set as a highlight (see also figure 4).

Figure 4 shows a perspective view of the chiller body 48 and fan 66 assigned to chiller body 48. The cooling body 48 has the lateral surface 60.2, the which forms in joint action with the lateral surface 58.2 of the cooler body 46 heat absorption zone 61.2 (see Figure 2), along which units of power 26 of row 32.2 in the assembled state of the arrangement of heating device 28. The cooling body 48 has also a partial zone configured as plateau 82, which it is formed by an upper side that is directed towards the media heating 24 in the mounted state of the device heating 10.

In the assembled state of the device arrangement of heating 28, each of the heating means 24 of the heating modules 22 is arranged above the plateau 82, seen from the cooking plate 14. Also, of the plateau 82 are formed openings 84, which they continue as air channels drilled through the body cooler 48 and vertically with respect to the level of the Upland. Through these openings 84, a stream of air it can be taken inside the chiller body 48 or to the outside of the cooler body 48. When this happens, you can especially achieve effective cooling of the means of heating 24 arranged above the plateau 82. Also, a lower side 86 of the cooling body 48, which is arranged in front of the plateau 82, it has nerves 88, which they form heat evacuation channels 89 (see also figure 5). Through these heat evacuation channels 89, which are extend in the direction of the main extension of the body cooler 48 and, in the assembled state of the arrangement of heating device 28, along axis 34 of the array arrangement, compensation of especially effective temperature between areas of the cooling body 48. The lower side of the cooler body 46 is configured as identically, so that the heat evacuation channels 89 formed by the ribs 88 continue in the cooling body 46 and, therefore, they run throughout the unit of cooling bodies 42 a along axis 34.

By arranging the heating means 24 through of the plateau 82 and the arrangement of the power units 26 next to the heat absorption zones 61.1, 61.2 of the body cooler 48, power units 26 are shielded partially through the plateau 82 against the field of heating generated by the heating means 24. Al this happen, partial zones 94, 96 of the cooler body 48, each one of which extends through the area of the means of heating 24, serve as a means of protection to protect power units 26 against the heating field. The zones partial 94, 96 correspond to areas of the cooling body 48, on each of which a means of overlapping heating 24. These appear in the figure delimited in a way Schematic by dashed lines.
